To alt whom it* may concer-n,

Be it known that I, Entire A. LAUeHLxN,

a citizenoii the United States of' Amerfa,

and a resident of lChicago, county .et Cook,-

and State of Illinois, have invented certain new and useful Improvementsin Side Bearings, of which the following is 'a specilication. IThisinvention relateste side bearings for railway cars. i

The main objects of the invention are side bearing suitabley for use oneither the car orthe truck bolster, and. te. provide a housing designedso .as teadinit .of pessilia wear plate through the roller opening andsecuring it to the housing after a roller is in again coming intoalinement with'theopen- Qingin the housing.

place inthe housing Iin such manner as to prevent removal of theroller., 4

An illustrative' embodiment of this invention is shown intheacoempanying draw# ings in which- A,

Figure l is a side elevation of the` side bearing as it would appearwhen secured to the bolster of a car'body.v Fig. 2 is a longitudinalsectional viewof the bearing. Fig. 3 is a transverse vertical sectiontaken on the line A--A of Fig. 1.

It is desirable torso construct side bearings for railway oars that thebearings may be shipped as complete` units and not be liable to haveparts of4 the bearings become disengaged therefrom either before orduring service. To accomplish this end it has been customary to makethe-housing of the bearings in separable parts so that said partsl maybe secured together 'after 'the .wearing plates and rollers have beenassemthrough which said shaft or trunnions may.

be inserted to be fitted. within the roller. The side bearing is alsodesigned to receive a wearing plate after the roller has thus beenassembled with the housing,l said `wearing plate serving to prevent theshaft from eferring to the drawings, a housing 1 is shown having asolidtop 2, side walls 3, and end walls 4. The bearing is secured to thehasta or the @ar body or. shaman. ai um ltruck by rbolts passing throughthe 'y The shaft 10 is .separable from the roller 11 and .the side wallsf3 are provided with may roller 1l, but in .orderto bring the @mining13g of. .the roller which remises shaft l@ n l fore the wear plate 5is'secured to housing 1, as whenv the wear plate isin position itprevents the roller 11 from being alined with the openings 12. After theshaft 10 has been fitted within the roller 11 the roller is pushed to'one side as indicated by the dotted lines 13.2. This leavesA plenty 'ofremove the shaft 10 from -roller 11- as the wear plate prevents theroller from being moved back to the position indicated b the dottedlines 13.1 where its shaft may e in alinement withthe openings 12.

The operation of the device is similar to that described in ap licantscopending application ASerial No. 56,491, filed March 24, 1913, butbriefly it may be said that cars are ter bearing but rocked from side toside with respect to the trucks, and thereby require side bearings tolimit this rocking movement,` and also when the cars arerounding 16.Seated in a' depression in the part/"20l ,nie seti" was a. of thehousing @a alinement. with the openings 12 of the housmg 1, it isneessary that this. be dons .bs-:-

usually supported on their trucks by a censistance to such rotation willbe'less than the v tractive resistance between the roller and the terbearing,

curves one or theTotherfof ltheside bearings assists in 4supporting thecar. When one of the side bearings thus assists in supporting the car atthe time of rounding curves, the

roller 11 rolls between the wear plate 5 anda suitable Wearing surface14 on the truck. If the car turns 'so far that the ends of shaft 10arrive at the reduced ends 15 of the runways, the weight borne bythebearings will be transmittedl from the housing 1 to shaft 10, whereasnormally mitted direct from the upper wear plate 5 to the roller." Whenthe load is thus transferred from the wear plate 5 to the shaft 10,

"the roller may continue to rotate after reachingthe end y`of the runwayand the rethe weight is trans-A on 'a straight track.y When the from thespirit of this invention as defined by the following claim. v

I claim In aside bearing for railway cars, the combination of a roller,a houslng having an opening through whichsaid roller rotrudes, andhaving ways at opposite sides thereof, a wear plate in said housing'cooperating with said roller, said roller having a removable shaftextending into said ways, a retaining wall at the outer side of eachway, and said ways being greater in height at their centers than thediameter of said shaft and being suitably reduced in height at theirends whereby the load normally transmitted through said wear plate maybe transmitted through said shaft when the roller4 irs at the ends ofsaid ways, one of said retalning walls having therein an opening for thepassage of said shaft andV said wear plate being adapted to be insertedthrough said roller opening and ada ted when in Iplace to prevent saidshaft' roml registering with said shaft o enng. j 'Signed at AChicagothis 20t day of May 1913.
